MACHINE FOR GRIMPING PAPER FOR STICKING PINS.

Specification of Letters Patent No. 13,553, dated September 11, 1855.

To all whom it may concern:

Be it known that I, J. B. TERRY, of the city and county of Hartford, inthe State of Connecticut, have invented a certain new and usefulImprovement in Crimping Ar rangements of Pin-Stitching h/Iachines, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, which form part of thisspecification, and in which- Figure 1 represents a side elevation of thecrimping gear arrangement, showing the crimping clamps in their raisedposition and the jaws which hold the crimped paper open;Fig. 2, asimilar elevation viewed from the other side and representing thecrimping clamps as having crimped the paper over and around a former orrod as will hereinafter be fully described; Fig. 3, a similar view toFig. 2, but showing the former withdrawn and the crimping clamps at theextremity of their down stroke and the jaws advanced to hold the crimpedpaper; with diagram attached illustrative of the crimp with a pin stuckthrough. Fig. 4 represents an end elevation showing the parts in theirposition indicated in Fig. l; and Fig. 5 a further end elevationillustrations of the parts in their position represented in Fig. 3.

My invention has reference to that portion of pin sticking machineswhich stick the pins in rows in the strip or sheet of paper, thatcomprises what is termed the crimping arrangement. The other parts ofthe machine therefore will only be generally or partially alluded to, orwill for the most part be altogether omitted notice of, as-myimprovement is not confined to any one ma chine in particular but to awell known class of machines that stick the pins as just described, andof which description is the machine referred to in my patent of J anuary3rd 1854, and in which, the paper is fed forward at intervals, formedinto crimps at suitable distances apart by means of a crimping bar, thecrimped portions of the paper held by jaws while the pins are stuckthrough the crimps, then the jaws opened to let out the stuck crimp, anda further similar feed, crimp, and sticking operation proceeded with asbefore.

Having thus generally spoken of the operation, I will proceed todescribe in particular my improvement.

The paper, it will be observed, as inclicated by red line in Figs. 1, 2and 3 of the drawing, passes from the one side of the machine over aroller or other suitable device, downward to a position near the bedwhere it is crimped and off in a horizontal or other direction, much ina similar manner to that shown and described in my patent of 1854 asabove referred to, there being likewise a somewhat similar arrangementof grooved sliding jaws (a a) that are caused by any suitable mechanismto advance and recede and which by means of sprlngs, forceps or pins,serve to clasp the crimped portion of the paper and hold the crimp whilethe pins are being stuck through it.

My method of forming the crimp however is difi'erent to that describedin my former patent; I employ no fixed crimping bar or former, but use,under a peculiar arrangement and operation together, a sliding rod orformer and crimping clamp or their equivalents substantially as follows.The crimping clamps (b b) are shown hinged together at their upper end,where they are united to an operative lever (0), that, in connectionwith suitable side guides to the clamps, give the clamps an intermittentvertical movement as will presently be described. These crimping clamps(I) b) may be kept open by means of a spring between them, and closed atthe proper periods during their vertical movement, by projecting guides(e), in between which they slide. The lower ends or edges of the clamps(Z) 7)) are made with crimping lips immediately above which aresemi-circular recesses (f), running-one to either clamphorizontally ofthe clamps parallel with their crimping lips. These semi-circularrecesses (f) are for the purpose of receiving in between the clamps aformer or rod around which the paper is compressed by the clamps inclosing and serving as a bed or stop for the paper to enable the clampsto ive the requisite crimp to the paper. This former or rod is operatedso as to be withdrawn from between the clamps after the crimp is madeand the paper formed around the rod, and, at the proper period, again toshoot across or occupy the position specified for its reception betweenthe clamps, to eifect the crimping as follows: The clamps (b 1)) beingopen and at their top stroke as represented in Fig. 1, in descending,press upon the paper and carry it on or against or over the former orrod (g) which remains, for the present, stationary in its forwardposition across the race or path of the clamps. The clamps then closeand in so doing fold the paper around the rod or former (g) and, theformer acting as a bed or bearing, the clamps further squeeze the paperinto the requisite flat crimp beneath the former. During this closingaction of the clamps, or toward the finishing portion of the same, theirdescend ing movement is suspended and remains so for a short periodafter the clamps are closed, to enable the former or rod to be withdrawnout of the path or race Way of the clamps to the position occupied bysaid former (g) shown by dotted lines in Fig. 5, when the clamps (Z91)), still closed, are made to continue their descent from theirstationary or stopping position, represented in Fig. 2, to their extremedownward stroke shown in Fig. 3, which brings the cramped portion of thepaper in between the sliding jaws (a a) before referred to, the jawsmoving toward each other and by pin protections or other suitabledevices on their faces sticking into and holding the paper in betweenthem, while the clamps (b b), having thus conveyed the crimp to the jawsthat hold it for the pins to be stuck through the crimp, ascend to theiroriginal position, represented in Fig. 1, and the former or rod is againshot forward to its position represented in Figs. 1, 2 and 4, forrepetition of the crimping process as before. In

this manner a most perfect crimp is formed, one necessarily of uniformwidth and regularity, with a hollow arched or other equivalently shapedstrengthening rib at the root (m in diagram of Fig. 2) of the crimp,which will give the necessary firmness to the crimp in the stickingprocess; and as the crimp is formed before its adjustment to thesticking position and the former or rod withdrawn prior thereto, nointerference can by any possibility of defective construction, shake oraccident, be presented by the former to the passage of the pins throughthe crimp.

The crimping clamps (b b) may have their specified intermittentreciprocating vertical movement given them by any suitable arrangementof mechanical devices and may be thus operated by a spring (h) andsuitably formed cam (is) acting upon a lever arm (Z) attached andserving to rock the fulcrum to which the operative lever (0) of thecrimping clamps is afIiXed.

The former or rod (g) may have its specified period of rest, forward andwithdrawal movements given it, by a somewhat similar arrangement ofdevices as for instance by a revolving cam wheel (m) and a spring (a)brought to bear or act upon a lever (0) that by a jointed attachment (p)connects with the former (9) through a slot in a tube (8) in and out ofwhich the former is projected to effect the crimp or be withdrawn fromit as specified.

hat I claim as new and useful and desire to secure by Letters Patent,is-

The use of the hinged clamps (b b), or equivalents, operating togetherwith the folding rod or former (g) to crimp the paper, substantially asset forth.

In testimony whereof, I have hereunto subscribed my name.
